wmn TIE AND TOOL.

Application filed June 13, 1914.

larly to wire ties and tools adapted for use" in connection with rubber hose.

Ties of various forms have previously been used for securing sections of rubber hose to couplings and similar members. These ties have, however, required the use of complicated and expensive tools to lock the same in place and the ties have heretofore been of such form that loose, sharp ends are left when the tie is locked which interfere with the handling of the hose.

-Moreover ties heretofore used have failed in that theycould not be drawn tightly enough to give .a'satisfactory binding action owing to the fact that the tools used do not give an even tension on the ties during the looking operation.

One of the principal objects of my invention is to provide a wire tie and tool for locking the same which may be easily and ,efiectively applied to rubber hose to securely bind the hose to the connections.

A further object of my invention islto provide a tie, the loops of which are normally spaced apart, and a tool adapted to draw the loops first one over the other and subsequently twist them into interlocked relation.

A. still further object of my invention is to provide a tie and tool of simple construction which will be efiicient, easy to operate.

and cheap to manufacture.

Other objects and advantages of the invention will be apparent as the same is better understood from the following description, when taken in connection with the accompanying drawing, in which Figure 1 is aside elevation of a tool according to my-invention; Fig. 2 is a plan view of the wire tie; Fig. 3 is a perspective View showing the tool in position to draw the ends of the loop one over the other;

Fig. 4 is a side elevation showing the position of the tool and tie before the loops have been interengaged; Fig. 5 1s a side Specification of Letters Patent.

elevation showing in dotted lines the posi-' tion of the tool after the loops have been twisted into interlocked relationship; Fig. 6 1s a perspective 'view'showingthe tie after the loops are inter-engaged, and Fig. 7 is 2m elevation showing the tie locked in posiion.

On the drawing, 1 indicates a locking tool according to my invention having at one end a sharpened portion 2 and at the other a toe 3. The tool maybe formed of suitable material having a circular cross section. The tie is shown in Fig. '2 and com prises an oblong-shaped wire loop designated as 4 and having at the center of one end a kink 5, the purpose of which will hereafter appear. The loop is slightly narrower at the end 6 opposite the end having the kink 5 in Iprder that the end 6 may be drawn betwee the sides of the loop when the tie is locked; The tie 4 is composed of wire bent to, the required form, the ends of the. wire beingjsu itably attached to each other as indicatedat The/length of the loopis approkirii'ately i-equalto the circumference of .the'ho se upon which it is to be used plus thelthickness, he.lockii1g tool.

The use bfinyinvention." is illustrated in Figs. 3 to'a'l. 'j-The ti'e 4 is first-bent about the hose as'indicated iii 3 until the ends v are in the position; indicated more clearly in Fig. .4". Theto'ol' 1- is then inserted'through the wider end of thefjtie with the shank engaging the kinlro and" the toe 3 engaging the opposite end of -the tie. The shank of the tool is then moved in the direction indi- Jated by the arrows in Figs. 4 and 5 to draw the narrowend of the loop through the wider end into the position shown in Fig. 6. In this connection it willbe noted that the. kink 5 furnishes a bearingf fo r thel'shankof the tool causingthe same'to automatically center itself in the'end of thefloop so that the end '6 will be dr awn'squarely throughIthe wider end of the loop and tension will be; exerted equally on both sides of the loop to-bind the same about the hose. Whenthe ends of the tie have interengaged, as shown in Fig.6, the tool may be reversed with the pointed end 2 engaging the kink 5 and the end 6 may be easily bent to the position indicated in Fig. 7. In this position the tie forms a comparatively smooth connection, having no rough ends or surfaces to interfere with the ham diing the hose.

It will be apparent that I have invented a tie for use with rubber hose which has many advantages over the ties of the prior art. My ties and the-tools for locking the same are comparatively inexpensive. During the locking operation, owing to the kink 5 in the end of the loop, both sides of the tie are drawn with an even tension, so that both grip the rubber tubing with equal force. During the operation of locking, the loop is slightly elongated and the wires slightly.

stretched, and the locking operation proceeds while tension is being exerted on the wires. 111 this way a better gripping action than is possible with any of the devices of the prior art is obtained. My invention is particularly valuable for use in connection with hose of one inch or less diameter, but may be used with larger hose with equally good results.

It is thought that the invention and many of its attendant advantages will be apparent from the foregoing without further description, 1t being understood that various changes may be made 111 the form and construction of the tie and tool without departing from the spirit and scope of the invention or sacrificing any of its advantages, the form hereinbefore described being merely one preferred embodiment thereof.

1 claim:

In a device of the character described, the combination of an oblong-shaped loop, one end of which is wider than the other, a rounded kink in the center of the wide end thereof, and a one pieee tool for engaging the loop to draw the ends together comprising an elongated shank, circular in cross-section, adapted to bear in said kink and an integral toe adapted to engage the narrower end of said loop, the length of the loop being approximately equal to the circumference of the article to be tied plus the diameter of the shank of the locking tool.
